A nurse is initiating bladder retraining for a client who has urge urinary incontinence. Which of the following instructions should the nurse give the client?

A. "Limit your fluid intake to 500 milliliters per day.": Severely restricting fluid intake can lead to dehydration and concentrated urine, which can irritate the bladder and worsen incontinence. Adequate hydration is essential during bladder retraining. B. "Take your diuretic medication with your evening meal.": Diuretics should generally be taken in the morning to avoid nocturia and sleep disturbances, which could interfere with bladder retraining efforts. Evening dosing may exacerbate incontinence at night. C. "Plan to urinate every 3 hours while you are awake.": Scheduled voiding is a core strategy in bladder retraining. Urinating at regular intervals, such as every 2–3 hours, helps the bladder gradually increase its capacity and reduces episodes of urge incontinence. D. "Decrease your intake of cranberry juice.": While certain irritants like caffeine, alcohol, and carbonated beverages should be avoided, cranberry juice is not a primary bladder irritant for most. In fact, it is often encouraged to prevent urinary tract infections (UTIs), which can cause temporary urge incontinence.
